Sodium hydride (6.4 mg, 0.16 mmol, 60% in mineral oil) was added to a solution of 1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (15 mg, 0.080 mmol, Example 2, Step 5) in DMF (2.2 mL). After stirring for 10 minutes, 1-bromo-2-phenylethane (22 μL, 0.16 mmol, Aldrich) was added dropwise. After stirring for 1 hour, additional sodium hydride (3.2 mg, 0.080 mmol, 60% in mineral oil) and 1-bromo-2-phenylethane (11 μL, 0.080 mmol) were added. The crude reaction mixture was diluted with water and MeOH, filtered and purified by preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH) to afford product as a light yellow powder (4.8 mg, 20%).
